To all wlwm. itmay comm:

Be it known that I, FRANCK MINUTILLO, residing at 157 E. 110 Street, borough of Manhattan, and post ofiice at 1 57 E. 110

5 Street, borough of Manhattan, city of New York, New York County, and New York State, and a citizen of the United States, have invented certain new and useful Improvements in Collapsible Horns, of which 10 the following is'a s ecification.

This invention re ates to megaphones or horns and more especially to collapsible horns and the object of the invention is to afford a means for extending and opening 15 the horn or collapsing and storing the same within a box or cabinet and in connection with a graphophone, so that when the containing box is closed and the device is inoperative the horn, made of telescopi tions, is collapsed. But as the lid iii said box is raised certain novel mechanism automatically connects the sections and elongates the horn for the amplification of the sound from the graphophone.

These and other details of the invention are more fully described in the followin specification, set forth in the appended claims and shown in the drawings, wherein Figure 1 is a side view of the improved horn and its operating mechanism.

Fig. 2 is a front view of the same.

7 Fig. 3 is a fragmentary sectionalview.

Fig. 4.- is a side view of the cabinet open with modified mechanism.

Fig. 5 is a similar View with the cabinet closed and partly in section.

Fig. 6 is a detailed sectional view.

'lhe horn is shown as mounted on the ordlnary graphophone box 10 having the recessed lid 11 hinged at one side of the same and having the usual rotating disc 12, sound box 13 and sound armld, the latter communicating with a sound chamber 15 on which the lower end of the horn is located as best shown in Figs. 1 and 5.

The horn comprises annular sections 16 each suficiently' larger than its preceding companion to permit same to telescope within the larger section and each section 16 has inward flange 17 and an outward flange 18 that prevent the release 6f the two adjacent ring sections at one end but prevent absolute freedom of movement.

SEC-

accompanying front of the box 10 is a shaft 20 on which is mounted arms 21 that carry at their outer ends the studs 22 of the outer ring section- 23 of the horn and to the shaft 20 is also secured an arm 24 that is connected by nieansof the rod 25 with a bracket 26' carried bythe lid 11, and as will be seen in Figs. 1 and 2, as the lid is in its open position the yoke comprising the shaft 20 and arms 21 extends the collapsible horn to its extended and operative position.

When the lid is closed the arms 21 are thrown down and the sectional rings of the horn collapsed within themselves, and the phonograph and horn is compactly housed.

In the modified form shown in Figs. 4 and 5 the arms 21 are carried by the shaft 20 and carry the ring 23 as above described. l

The arms carry the link 26 with the toe 27 that freely move. backward when the lid closes and the rod 28 through the bracket 29 actfuates said link 26, but'with the forward action ofthe link the toe 27 engages one of the arms 21 and throws it upward, elongating the horn.

To insure the even movement oi. the ring sections each ring may carry a loop 30 through which passes a rod 31 that is a sector of the are on which the loops 30 pass,

the rod being secured to the ring 23 and readily closes within the box 10.

The arrangement of these arms and rods in their collapsed position is shown in Fig. 5 where the l d is closed and the horn in its inoperative condition.

It is obvious that the parts may be further altered and modified without departing from the essential features above shown or from the scope of the appended claims.

Any desired number of sections may be used to add to the length of this horn and the dimensions of the arms increased to provide for this addition, thus providing a horn of far superior powers than the short devicefcommonly used in cabinets.

As shown in Figs. 4 and 5.the outer ring 23 may be flared to give a better dispensing eflect to the sound waves, and in Fig. 6 is shown how the lower and smallest section 32 is secured to the floor oi the box 10 and the sound chamber 15. The section 32 has 'the flange 33 that fits against the floor of the box and a tubular extension 34 is threaded to screw into a hole in the sound chamber, thus firmly securing the horn to the What I claim is:

1. In a phonograph cabinet, the combination of container having a sound compartment, a colla sible horn made up of ring sections, a lid to the container, and means connecting the horn and the lid to cause the horn to open in one direction while the lid opens in the opposite direction.

2. In a phonograph cabinet, the combina- -tion of a container having a sound compartment, a vcollapsible horn comprising interlocking sections, and secured to the cover of the sound compartment, arms pivoted to the container and carrying the outer section of the ho a lid to the container, and means connecte with the lid and ads ted to raise the arms when the lid is opene 3. In a phonograph cabinet, the combination of a container having a sound receivin chamber at one end and a hinged lid, a co lapsible horn made u of interlocking telescopic sections, an en section comprising a coupling ada ted to be secured to the sound receiving c amber, a pivotal bar, carrying arms, a larger and outer section of the horn carried by the arms, a. depending arm on the bar, and a link connecting the depending arm with the lid and adapted to extend thehorn when the lid is raised.

In testimony whereof I hereunto afiix my signature.

FRANCK MINUTILLO.
